• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang van hoe. hieu van ((((nam luc) OR (nam duoc))) or (nam thuc)) va danh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang van hoe. hieu van ((((nam luc) OR (nam duoc))) OR (nam thuc)) va danh va cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang van hoe. hieu van ((((nam luc) OR (nam duoc))) or (nam thuc)) va danh va cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang van hoe. hieu van ((((nam luc) OR (nam duoc))) or (nam thuc)) va danh va cuu tre*.
